.Sh BUGS
|
|
Interrupt handling, packet queuing and hardware clipping for the
|
|
.Li PXG
|
|
are totally broken. Support for the
|
|
.Li i860
|
|
co-processor must first be added.
|
|
.Pp
|
|
The X server is a work in progress.
|
|
.Pp
|
|
3D geometry acceleration is not supported, and probably never will be.
|
|
.Pp
|
|
Only one of the listed boards can be installed at any given time. Work is
|
|
underway to remove this restriction.
